    As I understand it, defragging the registry is more akin to removing the unnecessary "wasted" space in it. Microsoft don't recommend you defrag your registry.

    MS has its own tool to defragment registry, but it does not work on 10.

    PageDefrag defragments the files that make up the registry. As these files are in continuous use they cannot be defragmented while Windows is running. Defragmenting the registry itself is quite different. When registry entries are deleted they leave holes of unused space in the registry which would be filled in when registry entries are created. Removing these holes when the entries were deleted would have a serious impact on performance. Defragmenting the registry reorganizes the registry structure to eliminate the holes.

    If you feel this is necessary I would recommend doing an image backup first. Better to be safe than sorry.

    That is registry defragmentation, registry defrag does the same. It is harmless.

    When you run PageDefrag (pagedfrg.exe) you will be presented a listbox that tells you how many clusters make up your paging files, event log files, and Registry hives (SAM, SYSTEM, SYSTEM.ALT, SECURITY, SOFTWARE, .DEFAULT), as well as how many fragments those files are in. If you feel that these files are fragmented enough to warrant a shot at defragmenting them, or if you want to defragment them at every boot, select the appropriate radio button choice and click OK.

    I found out the other day that I can defragment registry when using Windows Defender AV but no when using AVAST (It seems AVAST locks it).

    Sounds like another good reason to get rid of Avast

    He meant he can do that when using Windows Defender as his antivirus. Not that Windows Defender does it.

    Does defraying the registry save space?
    How do I do this?

    It does not save enough space to matter in my opinion. In the screen shot posted at the bottom of page 1 of this thread you can see it is only 77 MB. I personally have not used a registry defrag program since windows 7. I will let another user post with a program they use for that.
